Specification of Letters Patent.

Application filed April 29, 1908. Serial No. 429,883.

To all whom it may concern:

Be it known that I, Enos T. BELL, citizen of the United States, residingat Spieeland, in the county of Henry and State of Indiana, have inventedcertain new and useful Improvements in \Vindow-Sha des, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

My invention relates to an improvement in window shades whereby theshade is suspended by a suitable cord depending from a pulley situatedat or above the top of the window frame, so that the said shade may beraised or lowered to any desired position in front of or below thewindow to which it is applied, and whereby said shade may be furled fromthe bottom end portion thereof, as will be hereinafter more fully setforth in the specification and particularly pointed out in the claims.

The object of this invention is to provide a means whereby the bottomportion of the shade may be furled without changing the position of theshade thereof, and whereby the shade thus furled may be moved into anyposition in front of or below the window to cover all or any desiredportion thereof in order to entirely shut out the direct rays of lightor to permit them to pass over the top end portion of the shade or belowthe bottom end portion thereof, or both as desired. I attain this objectby means of the shade illustrated in the accompanying drawings in whichlike numerals of reference designate like parts throughout the severalviews.

Figure 1 is an elevational view of my invention of a window shadeapplied to a window; Fig. 2 is a sectional view of the same taken alongthe line 2-2 in Fig.1; Fig. 3 is a view similar to that of Fig. 1showing the bottom portion of the shade drawn up or furled; Fig. 4 is asectional view of Fig. 3 and taken along the line 44 in Fig. 3; and,Fig. 5 is an enlarged detail view of the pulis carried.

The shade l is provided with an upper stretcher bar 2, and a lowerstretcher bar 3, both of which are connected to the shade in the usualwell known manner. Intermediate the top and bottom ends of the shade areformed folds or pockets which extend in parallel relation to each otheracross the shade and into which the top, middle, and l lowerintermediate stretcher bars 4, 5, and 6 are introduced to extend acrossthe shade for the purpose of not only operating as a stretcher for theshade, but also, for the purpose of carrying the guiding means for thesuspension cord l4 whereby the said cord is maintained in position, andalso to operate as a means for stretching the shade, preventing itscreasing, and folding it. The greater or lesser number of intermediatebars may be employed in connection with the shade, according as agreater or lesser number of the folds is desired in said shade, to foldthe latter into a smaller compass.

The suspension cord pulley 7 is situated centrally above the window 8 towhich the shade is to be applied, and is secured to the top rail 5) ofthe window frame. A suspension cord pulley 10, similar to the suspensioncord pulley '7, is situated centrally on and secured to the upperstretcher bar 2, to be in alinement with the pulley 7. Secured centrallyto said stretcher bars 4 and 5, in vertical alinement to each other andthe suspension cord pulley 10, are the guide eyes 11 and 12, and securedcentrally on the stretcher bar 6 is the fastening eye 13 to which oneend of the suspension and draw cord 14 is secured whereby the shade 1 isdrawn up and folded, as shown in Fig. 4. The said guide eyes 11 and 12,and the fastening eyes operate to not only maintain the shade invertical alinement when the draw end portion of the draw cord 14 isbeing drawn up wholly or partially, but also to operate as stops wherebythe depth of the folds of the shade are limited.

The suspension cord 14 is preferably of one piece and the blind liftingend portion thereof is passed over the suspension cord pulley 7, thenceto the top bar 2 of the blind to which it is secured at its end to thecenter portion of the top stretcher bar 2; the other end portion of thesuspension cord is passed over the suspension cord pulley 10, mounted onthe stretcher bar 2, thence down through the guiding eyes 11 and 12,thence to the fastening eye 13 to which this end of said cord 14 issecured, thus the lower portion of the shade 1 may be drawn up andfolded, as shown particularly in Figs. 3 and 4.

The suspension cord pulleys 7 and 10 are alike in form and operation.The pulley 7 whereby the suspension cord 14 is carried, is

situated centrally above or at the central portion of the rail 9 of thewindow frame of the window 8 to which the shade is to be ap plied, andsaid pulley is provided with cord grooves 16 which are inclined and leadfrom the smaller central portion of the pulley to the larger end portionthereof, so that, when the loose depending end of the suspension cord14; is directed downwardly and toward the smaller diameter of thepulley, said cord will freely pass around the center of said pulley tolower the shade and will have no tendency to follow either of thegrooves of the pulley to climb to the larger diameters thereof; but,immediately the depending slack end of said cord let is guided ordirected to either side of said pulley, said cord will immediatelyfollow that outwardly in clined groove situated at the side to whichsaid cord is directed and will climb, with the assistance of the guidingfingers 17, that larger end of said cord pulley to which said cord isdirected to be locked or wedged between the larger diameter of thepulley and the root of the guide fingers 18. This construction ofcord-pulley, however, is not absolutely necessary to the proper practiceof my invention, as any other cord-pulley of approved construction,whereby the suspension cord of the shade may be manipulated to adjustthe position of the shade may be used in connection with my invention,but I prefer to use the above described cord-pulley, as the same hasbeen found to be particularly adapted to this invention.

The shade 1 being suspended by the cord lat extending over the pulley 7may be readily raised or lowered to expose that top portion of thewindow above the shade. That end of the suspension cord 14 passed overthe suspension pulley 10 secured to the stretcher bar 2 may beindependently operated by that portion of the suspension cord extendingover the pulley 10 when it is found desirable to admit light through thebottom portion of the window. The bottom portion of the suspension cordlet is drawn to raise the bottom stretching bar 3, and the bottomportion of the shade 1 to expose the lower portion of the window, asshown in Fig. 3 to admit light therethrough.

It is obvious that a greater or lesser number of intermediate stretcherbars may be used in connection with the shade 1, according as the shadeis made longer or shorter.

I claim:

1. The combination with a depending win dow shade, of a suspension cordpulley situated at or above the top of the window to which said shade isapplied, a suspension cord extending over said pulley and connected at acentral point of the top end of said shade, a stretcher bar situated toextend along the top end of said shade, a lower stretcher bar situatedto extend across the lower portion of said shade, and a secondcordpulley situated centrally and vertically under said first suspensionpulley, so that the other end of the cord may be extended over thelatter cord pulley and be connected at one end to the lower stretcherbar of said shade.

2. The combination with a depending window shade, of a suspension cordpulley situated at or above the top of the window to which said shade isapplied, a suspension cord extending over said pulley and connected at acentral point of the top end of said shade, a stretcher bar situated toextend along the top end of said shade, a lower stretcher barintermediate the top and bottom ends of said shade, and a second cordpulley situated centrally and vertically under said first suspensionpulley, so that the other end of the cord may be extended over thelatter cord pulley and be connected at' one end to the lowerintermediate stretcher bar of said shade.

3. The combination with a depending window shade, of a suspension cordpulley situated at or above the top of the window to which said shade isapplied, a suspension cord extending over said pulley and connected at acentral point of the top end of said shade, a stretcher bar situated toextend along the top end of said shade, a lower stretcher barintermediate the top and bot tom ends of said shade, and a second cordpulley situated centrally on said first named stretcher bar andvertically under said first suspension cord pulley, so that the drawportion of the suspension cord may extend over the latter cord pulleyand be connected at one end to the lower intermediate stretcher bar ofsaid shade.

4. The combination with a depending window shade, a cord pulley situatedat or above the top of the window to which said shade is applied, asuspension cord connected at one end to the top end of said shade andextending over said cord pulley, a stretcher bar situated to extendalong the top end of said shade, a second cord pulley situated centrallyon said stretcher bar, stretching bars situated intermediate the ends ofsaid shade to extend across the same, and cord guides situated centrallyon the latter upper intermediate stretcher bars, so that the other endof the suspension cord may be extended over the latter pulley, throughsaid guides and be connected at its end to the lower of the series ofintermediate stretcher bars.

The combination with a depending window shade, stretcher bars extendingalong the bottom and top ends of said shade, stretcher bars situatedintermediate the ends of said shade to extend across the same, a cordpulley situated at or above the top of the window to which said shade isapplied,

and a suspension cord extending over said pulley and connected at itsend to a central portion of the top bar of the series of said stretcherbars, of a cord pulley situated centrally on said top stretcher bar, andguiding eyes situated centrally on the upper series 01 intermediatestretcher bars, so that the other end of the suspension cord may beextended over said latter cord pulley down through said guiding eyes andbe connected at its end 1 to the central portion of the lower of theseries of said intermediate stretcher bars.
